CYLINDER-BY-CYLINDER AIR-FUEL RATIO CONTROLLER FOR INTERNAL COMBUSTION ENGINE - When executing a Local-learning, an air-fuel ratio detecting time is corrected so that a dispersion of detection values of an air-fuel ratio sensor becomes a maximum value in one cycle of an engine. While executing a cylinder-by-cylinder air-fuel ratio control, a Global-learning is executed. In the Global-learning, the air-fuel ratio detecting time is corrected based on a relationship between a variation in estimated air fuel ratio of each cylinder and a variation in fuel quantity correction value of each cylinder. In the Global-learning, a computer computes a correlation coefficient between the variation in estimated air-fuel ratio and the variation in fuel quantity correction value of the cylinder for each case where the cylinder assumed to correspond to the estimated air fuel ratio is hypothetically varied in multiple ways. Then, the air-fuel ratio detecting time is corrected so that this correlation coefficient becomes a maximum value.

COMMUNICATION TERMINAL, COMMUNICATION METHOD, AND COMMUNICATION PROGRAM - According to an aspect of an embodiment, a communication terminal connectable to a communication network system transmits user data obtained by one communication terminal gaining a voice to other communication terminals through a network. The communication terminal includes a transmitter, a receiver, a voice request part which receives a voice gain request from a user, a voice gain recognition part which recognizes that the voice is gained, a data obtaining part which obtains user data, a data storage which stores data, and a data management part which causes the data storage to store the user data after receiving a voice gain request and which receives the recognition of the voice gain. The transmitter transmits the user data part after receiving the voice gain request from the user.

TASK EXECUTION CONTROLLER, TASK EXECUTION CONTROL SYSTEM, AND TASK EXECUTION CONTROL METHOD - A task execution controller includes a context generating unit that generates context information concerning a user and a surrounding situation of the user; a task managing unit that stores multiple tasks the user attempts to execute, selects a task according to the context information and a predetermined task selection rule, and controls execution of the task; and a service managing unit that confirms services executed by a device used for execution of the task, gives notification of a service corresponding to the execution of the task selected by the task managing unit, to the device and causes the device to perform the service. The task managing unit selects a task by using, as the task selection rule, information of priority levels of tasks and an execution-related dependency relation between tasks preset among the tasks.
